Background: Orthokeratinized odontogenic cyst (OOC) is a rare developmental odontogenic cyst that is clinically and histomorphologically different than odontogenic keratocyst (OKC). Case Description: OOC is a distinct entity from OKC with a unique biological behavior, pathogenesis, and prognosis. The distinction between these entities is paramount because unlike OKCs, OOCs rarely recur after simple enucleation and are not associated with nevoid basal cell carcinoma syndrome. We present a case of an 8-year-old male with an OOC of the right posterior mandible along with a differential diagnosis and discussion of OOCs and its common mimics. [ABSTRACT FROM AUTHOR]

ABSTRACTBackground Solitary oral mucosal xanthogranuloma, previously termed juvenile xanthogranuloma, is exceedingly rare in adults. Extracutaneous lesions are similarly rarely seen; and the condition generally affects infants and children.Methods This case report documents only the second occurrence of an adult oral xanthogranuloma on the palatal mucosa. For the clinician, a differential diagnosis is presented to include several disease categories, including traumatic, infectious/inflammatory, and neoplastic.Conclusions General dentists, dental specialists, and pathologists should be cognizant of this disease, and xanthogranuloma should be considered in the differential diagnosis of benign tumors of the palatal and oral mucosa, especially when a histiocytic entity is being considered.Practical Implications Dentists, dermatologists, and general practitioners may be the first to recognize this rare condition during inspection of the oral cavity.Continuing Education Credit Available: The practice worksheet is available online in the supplemental material tab for this article.A CDA Continuing Education quiz is online for this article: https://www.cdapresents360.com/learn/catalog/view/20

Abstract: This article is a review of the history of the clinicopathologic conference, a teaching method used for and by physicians in medical schools and hospitals throughout the United States since the beginning of the 20th century. [Copyright &y& Elsevier]

To determine the current level of use, characteristics, and perceived value of the clinicopathologic conference (CPC), we sent a 22-item survey questionnaire to the program directors of internal medicine residency training programs. Of the 278 residency training programs that returned questionnaires, 221 (80%) indicated that they held CPCs regularly. The conference received a mean rating (Likert scale 1 = best to 5 = worst) of 2.2 (95% confidence interval 2.2, 2. 3) for both its perceived educational value and its popularity. The CPC remains widely used in internal medicine training programs. Although relatively few programs have rigorous guidelines for preparation and evaluation of their presentations, the CPC is generally viewed as being popular and having sound educational value.
